ASVAB practice test/Army body fat calculator

Army body fat calculator

Waist ÷ height must be under 0.55.

Check my ratio

The Army replaced its body fat tape test with a waist-to-height ratio on 7 July 2026. Your waist at the navel, divided by your height, both in inches, must come out below 0.55.

0.514 · meets the standard

Waist ÷ height = 0.514, recorded to three decimals with the rest dropped. It must be below 0.55.

At this height the largest waist that meets the standard is 38.4 in.

The Army measures in inches; the ratio is the same in centimeters because the units cancel.

How the Army checks it now

Where the Army measures: waist at the navel, and height from floor to head.Waisttape level at the navelHeightin inches
Divide the waist by the height. The Army wants the answer strictly below 0.55.
  1. Waist circumference is measured at the navel (belly button), in inches.
  2. That number is divided by height in inches.
  3. Strictly below 0.55 meets the standard. The Army FAQ adds that the ratio is recorded to three decimals and not rounded, with later digits dropped, so .549 passes and .550 fails.
  4. At or above 0.55, a different team measures again the same duty day before any administrative action.

Worked example

A Soldier is 70 inches tall.

WaistWaist ÷ 70Result
36 in0.514Meets the standard
38.4 in0.548Meets the standard (the largest waist that does)
38.5 in0.550Does not meet it
39 in0.557Does not meet it

36 ÷ 70 = 0.51428, cut off to 0.514. At 70 inches the limit is 70 × 0.55 = 38.5, and the ratio has to be below it, so 38.4 is the largest waist to the tenth of an inch that passes.

If you are at or above 0.55

  1. A reading of 0.55 or higher triggers a confirmation measurement by a different team on the same duty day. It must happen before the commander takes any action.
  2. A Soldier at 0.55 or greater is flagged and enrolled in the Army Body Composition Program. The flag (code K) does not transfer with you.
  3. Regular Army and Active Guard Reserve Soldiers: the commander requests a medical exam to check for an underlying condition behind weight gain or an inability to meet the standard. National Guard and Reserve Soldiers may request one if they have reason to believe there is such a condition, at their own expense when not on active duty.
  4. The monthly assessments and progression requirements that used to apply while enrolled are rescinded. Commanders decide when to reassess, and remove you from the program as soon as you meet 0.55.
  5. Units may start separation action for a flagged Soldier, but no Soldier will be separated until HQDA completes its 180-day assessment and issues further guidance.
  6. Enrollment, disenrollment, counseling and other administrative actions otherwise still follow AR 600-9.

Who it covers and how it runs

  • The Regular Army, Army National Guard and Army Reserve, plus cadets at the U.S. Military Academy and in Senior ROTC. It also applies to retention actions and to military schools and institutional training, where it feeds graduation requirements.
  • Existing medical exemptions for pregnant and postpartum Soldiers remain in effect (per the Army FAQ).
  • Screening happens at least twice per calendar year, and a commander can direct one at any time.
  • Units must allow at least seven days between an AFT or CFT and the screening, unless the commander modifies that for operational demands.
  • Every Soldier needed a WHtR recorded in ATIS within 90 days of the directive’s date.
  • The policy is not retroactive, and where it conflicts with other Army directives or regulations it controls. AR 600-9 has not been rewritten yet: G-1 is to fold the directive into AR 600-8-2 and AR 600-9 within two years, and the directive ends when they are revised.
  • The Army will review the standard for 180 days and may refine it, so confirm current rules with your unit.

ASVAB and AFQT scores explained

If you are looking at the Army because you plan to enlist, the score that matters first is your AFQT. It is built from four ASVAB subtests: Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR) and Mathematics Knowledge (MK). WK and PC combine into a verbal expression score (VE), and the composite is 2 × VE + AR + MK. That composite is converted to a percentile from 1 to 99 using an official table.

AFQT categoryPercentile
I93 to 99
II65 to 92
IIIA50 to 64
IIIB31 to 49
IVA21 to 30
IVB16 to 20
IVC10 to 15
V1 to 9

A higher percentile means more jobs and more branches open to you. The minimum AFQT to enlist depends on the branch and on whether you have a diploma or a GED, and it changes, so confirm it with a recruiter. The fastest way to raise the four subtests is to practice them: the free ASVAB practice test has questions with every answer explained, and the topic breakdown lets you drill arithmetic reasoning, math knowledge, word knowledge and paragraph comprehension one at a time.

Try 5 ASVAB-style questions

The ASVAB bank here currently has math questions only (algebra, geometry, rates, percentages, ratios and word problems), the kind that feed Arithmetic Reasoning and Mathematics Knowledge. It has no Word Knowledge or Paragraph Comprehension questions yet. Work each one, then open the answer.

  1. Q1Word problems

    A platoon of 48 soldiers is organized into fire teams of 8 soldiers each. If 16 soldiers are reassigned, how many full fire teams remain?

    1. A3 fire teams
    2. B4 fire teams
    3. C5 fire teams
    4. D6 fire teams
    Show answer

    B. 4 fire teams After 16 soldiers leave, 48 − 16 = 32 soldiers remain. Dividing by the fire team size: 32 ÷ 8 = 4 full fire teams. Choosing 6 ignores the reassignment entirely (48 ÷ 8 = 6). Always read carefully whether the problem asks for a before or after scenario.

  2. Q2Rate time distance

    A convoy travels at a constant speed of 45 mph. How many miles does the convoy cover in 3 hours?

    1. A120 miles
    2. B135 miles
    3. C150 miles
    4. D180 miles
    Show answer

    B. 135 miles Distance equals speed multiplied by time: 45 mph × 3 hours = 135 miles. The other answers result from arithmetic errors — for example, 45 × 4 = 180 or incorrectly adding the numbers. The distance formula D = R × T is fundamental to these problems.

  3. Q3Percentages

    A military base receives 200 cases of MREs. If 15% are vegetarian meals, how many vegetarian MREs are there?

    1. A25 cases
    2. B30 cases
    3. C35 cases
    4. D40 cases
    Show answer

    B. 30 cases To find 15% of 200, convert the percentage to a decimal (0.15) and multiply by the total: 0.15 × 200 = 30. The other choices come from misidentifying the percentage (25 is roughly 12.5%, 35 is 17.5%, 40 is 20%). Always convert the percent to a decimal before multiplying.

  4. Q4Algebra

    Solve for x: 3x + 7 = 22

    1. Ax = 3
    2. Bx = 4
    3. Cx = 5
    4. Dx = 7
    Show answer

    C. x = 5 Subtract 7 from both sides to get 3x = 15, then divide both sides by 3 to find x = 5. Check by substituting: 3(5) + 7 = 15 + 7 = 22, which confirms the solution. A common error is dividing 22 by 3 without first subtracting the constant term.

  5. Q5Geometry

    What is the perimeter of a rectangular training area that is 50 yards long and 30 yards wide?

    1. A80 yards
    2. B150 yards
    3. C160 yards
    4. D300 yards
    Show answer

    C. 160 yards Perimeter is the total distance around a shape. For a rectangle, P = 2(L + W) = 2(50 + 30) = 2(80) = 160 yards. The choice 150 is half the perimeter, and 300 is the area (50 × 30). Distinguishing perimeter from area is a key skill on the ASVAB.

Common questions

You no longer calculate a body fat percentage. The Army's screen is now the waist-to-height ratio: waist at the navel in inches divided by height in inches, which must come out below 0.55. The calculator above does the division and shows the largest waist that passes at your height.

There is no percentage to work out. The Army's July 2026 policy made the waist-to-height ratio the sole body composition assessment, replacing the height and weight tables and the tape test. Your result is a ratio such as 0.514.

Strictly below 0.55. The ratio is recorded to three decimals and not rounded; digits after the third are dropped, so .549 passes and .550 fails.

The Army's FAQ describes one standard for all Soldiers, with no adjustment tables. Existing medical exemptions for pregnant and postpartum Soldiers remain in effect.

No. The Army's FAQ says the tape test and all earlier body fat methods have been rescinded, and the waist-to-height ratio is the only authorized method. A different team does measure you a second time on the same duty day before any enrollment.

A second team measures you the same duty day. If you still fail, you are enrolled in the Army Body Composition Program and flagged until you meet the standard. Units may start separation action, but the directive says no Soldier will be separated until HQDA finishes its 180-day assessment and issues further guidance.

No. The exemption for an AFT score of 465 or higher was rescinded, so every Soldier must meet the waist-to-height standard whatever their fitness test score.

At least twice per calendar year. Units must leave at least seven days between an AFT or CFT and the screening unless the commander modifies that for operational reasons, and a commander can direct a check at any time.

The AFQT is the part of the ASVAB used to decide whether you qualify to enlist. It draws on four subtests: Word Knowledge and Paragraph Comprehension (together a verbal expression score), Arithmetic Reasoning and Mathematics Knowledge. The raw composite is commonly published as 2 × VE + AR + MK, and it is converted to a percentile from 1 to 99 with an official table that this page does not have, so it does not offer a percentile calculator.

The percentile is commonly grouped into categories: I is 93 to 99, II is 65 to 92, IIIA is 50 to 64, IIIB is 31 to 49, and IV and V are below that. Higher categories open more jobs. The minimum to enlist depends on the branch and on whether you hold a diploma or a GED, so ask a recruiter for the current figure.
